I wasn't aware of the significance of murukku in weddings. In Kerala weddings, murukku is included in the sweets and savories that was presented to the groom's house from the bride's family when the bride arrives at the groom's house. I don't know if those traditions are followed anymore. There are a lot of different variety sweets and savories available in the market now that has a higher status than the poor old murukku, unniyappam and the likes.
